A while back I posted of an idea to build an antenna rig that could pull in distant stations. I posted a how to. Well I finished the project.
Doesn't look pretty. But it's goal isn't to win a fashion contest. It's to get far away FM signals. It works perfectly!
BEST about this design. It's removable (easily). Does NOT damage or scratch the phone.
The only thing I must add. Is if you want to build this you will also need a very sharp knife to cut away the "rubber" coating and get to the plastic so the 3M tape and electrical tape will adhere.
Scraping the rubber coating off the case to get to bare plastic for better adhesion.
Placing 3M double sided tape on left side of case.
Attaching telescoping antenna to case WITH antenna lead attached (used 1 strand of Ethernet cable)
Putting a top layer of 3M tape to hold the antenna from pulling off and to better hold to case
With a SECOND layer on the back added as in image before. Began to add electrical tape to hold wire down and "clean" up the look of the case.
Project completed (back) with extra 3M tape added to hold the heavy headphone cable to case.
Phone in case and running FM Radio
All in all this cost over $25 but I now can get stations from as far away as 80 Miles and very weak stations previously unforeseen.
Alternatively this can be done with a simple headphone remote cable with the 4 connections on the jack. It will not be as strong.
Also I bought a RC Car transmitter antenna. It's VERY fragile. It may break. You might want to get a stronger antenna . The metal on this antenna is very thin so it has alot of "flex" in the sections.
